So i sent my ecu back to enthalpy and he said for some reason the original tune was for 700cc injectors so he switched it to 740cc and he added some timing to help with the s3 cams. It was running fine with this tune no hesitation etc.. but it wasn't making the power it should.
I got the ecu back and the car runs like crap, idles at 10 afrs, cruising is between 10-11afrs and it hesitates while cruising and it backfires. I lowered the fuel pressure but it only helps in boost but it still feels weak. I don't want to dyno it because it would be a waste of money. I can already tell that its making less power than before. I just hate having to wait a few days before even getting a response.
I'll lower the fuel pressure even more to see what happens. I'll double check the plugs and timing but nothing has changed from the previous tune. Hopefully the motor doesn't blow.
